BURNER.

SPECIFICATION forming part of Letters Patent N0.'e31,e22, dated August 22, 1899.

Application flied December 21.18198. sean 110.699,925. dromen.)

To all whom, t may concern:

Be it known that I, ERNEST CLIFTON DICK- ERSON, of San Antonio, in the county of Bexar and State of Texas, have invented anew and useful Improvement in Burners, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple and economic construction of burner adapted for oil or gasolene wherein a retort or vaporizer will be surrounded by a jacket or deiiector and wherein the retort or vaporizer will be directly in front of the valve admitting vapor to the burner, the arrangement of the vaporizer relative to the jacket i and that of the jacket and vaporizer relative to the vapor-supply valve being such that the burning vapor will entirely envelop the vaporizer, providing for an intense heat and a rapid and perfect production of vapor.

The invention consists in the novel construction and combination of the several parts,`as,will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improved burner and the supply -tank with which it is connected, a portion of the tank being broken away. Fig. 2 is a longitudinal vertical section through the improved burner and the vapor-supply valve, and Fig. 3 is a vertical transverse section taken practically on the line 3 3 of Fig. 2.

A represents a vaporizer provided with an interior chamber 10, adapted to be filled or partially filled with gravel, wire-gauze, tacks, or other objects adapted to assist in the breaking up of the body of liquid supplied to the chamber. The rear end 11 of the vaporizer A is conical, and the forward end is shown practically straight. The forward end of the vaporizer A is provided with a plug 12, which is held to turn therein, and` the said plug is provided with a channel 13, capable of `being brought in communication with an opening i 14, leading into the forward end of the gencrating-chamber 10 of the vaporizer. Usually the'plug 12 closes the opening 14; but when an exceedingly-intense iame is desired the plug is turned to bring its channel 13 in communication with the opening 14, and thus admit of more or less of the vapor in the generating-chamber being fed directly to the fiamevat the forward-end 0f the vaporizer. A pipe 15 is connected with the vaporizer A, preferably at the bottom and near the forward end, as shown in Figs. 1 and 2.y The pipe 15 is adapted to supply gasolene or oil to the generating-chamber 10 and is provided with a suitable valve 16, the-oil or gaso-v lene supply pipe 15 being connected usually with the bottom portion of a tank 17, as shown in Fig. 1. A tube 18 is connected with an air-valve 19, the said valve being located at the upper portion of the tank 17, ,and at the upper end of the tube 18 a bulb 2O is located. Thus by operating the bulb 20, the air-valve 19 being open, sufhcient airis forced into the tank to compel the liquid contained in said tank to iiow into the generating-chamber 10. After a sufficient pressure has been generated within the reservoir the valve 16 maybe opened and the burner operated for a considerable length of time without any necessity of recharging the reservoir with air under pressure.

In order that the burner may be raised or lowered, as occasion may demand, the tank is provided with trunnions 21 at its lends, and sleeves 22 are mounted to turn on said trunnions,vthe sleeves being connected with straps 23 or other devices or harness so constructed as to support the tank from the shoulders or body of the operator.

A pipe 24,adapted to convey vapor from the vaporizer to the burner-jet, is connected with the upper portion of the generating-chamber 10. The outlet 'of said vapor-delivery pipe 24 is preferably out of alinement with the oil or gasolene supply pipe 15, and the vaporsupply pipe 24 is carried to a point at the rear of the vaporizer A and down opposite the conical end 11 of the vaporizer, and at the lower end of the vapor-supply pipe a needle-valve 25 is located, the point whereof` directly faces the pointed portion of. the rear end ofthe vaporizer. A generating-cup 26 of any approved construction is attached to the bottom portion of the needle-valve casing. The vaporizer is surrounded by a jacket or a delector' B, shaped similar to the frustum IOO of a cone. The jacket or deiiector extends beyond both the forward and the rear ends of the vaporizer, the contracted end of the jacket or vaporizer being the end that surrounds the rear or conical portion of the vaporizer. The pipes l5 and 24 pass through the jacket or deflector and serve to hold it in position; but other means may be employed for this purpose, if desired, it being understood, however, that a space must intervene between the entire exterior surface of the vaporizer and the interior surface' of the jacket or deilector.

The particular object of this invention is to burn away the thorns from the cactus or prickly pear found in unlimited quantities in the southwest, which plant is good feed for stock; but in its natural state the stock cannot eat it, since nature provides each leaf with long sharp thorns. These thorns burn readily when a iiame is applied to them, and the removal of the thorns through the medium of a burner, such as has been described,leaves the growth in good shape, green and fresh, and the stock thrives on its nourishingr qualities when all else in the form of feed has been dried up by a prolonged drought.

In operation the needle-valve 25 and the valves 19 and 16 are opened and gasolene or oil is forced by operating the bulb 2O into the generating-chamber l0. When the burner is cold, the gasolene or oil will find its way through the pipe 24 into the gen erating-cup 26, and such oil is then ignited. The flame from the ignited oil in the generating-cup heats the Vaporizer A and vapor is generated, and the vapor finding an exit through the pipe 24 passes through the needle-valve and is directed to the conical end of the vaporizer, where it becomes ignited. As the vapor impinges on the pointed end of the vaporizer the burning vapor causes a suction and draws into the jacket or deilector sufficient air to effect perfect combustion, and the iame will entirely encircle the vaporizer, occupying virtually the entire space between the vaporizer and the jacket or deflector and finding an exit in a large volume from the outlet or front end of the jacket, thereby heating the vaporizer to a generating heat and prod ncing a perfect gas to supply both the valves and to keep lighted the flame which issues at the front end of the plug.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A burner consisting of a vaporizer, comprising a hollow body having one of its ends conically shaped, the interior of the vaporizer being adapted for generating vapor, a conical jacket or deliector, the smaller portion whereof is of greater diameter than the diam- .eter of the Vaporizer, .said vaporizer being contained within the said jacket or deflector, the conical end of the vaporizer being'at the contracted end of the jacket or dcector, a reservoir adapted to contain liquid fuel, a fuel-suppl y pipe connected with the reservoir and with the chamber of the vaporizer, a vapor-conducting pipe connected also with the chamber of the vaporizer, and a needle-valve carried by the vapor-conducting pipe, said valve facing the pointed end of the vaporizer, substantially as described.

2.
